More importantly CASA the airspace regulator hasn't directed that low level Class E be implemented (nor low level surveillance for that matter) because as yet they haven't deemed it necessary.
There is not much hope with any progress on Class E as CASA don't even understand Class G ! They certainly don't appreciate established culture and change, which is what has to be managed if there is to be any change at all. If they did, maybe we might be able to turn a page in this saga! Not holding my breath.
Merry Christmas
